Sound Waves

Front

What is amplitude in sound waves?

Back

Amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In sound waves, higher amplitude means louder sound.

What is vibration?

Back

Vibration is a rapid back-and-forth motion that can occur in solids, liquids, or gases, and is the primary mechanism through which sound is produced.

What does a wave transfer?

Back

A wave transfers energy, not matter.

What is the starting position of a wave?

Back

The starting position, also known as the equilibrium position, is the point where the wave would rest if there were no disturbances.

Front

What is amplitude in the context of a wave?

Back

Amplitude is the height of the wave from its equilibrium position to its peak, indicating the energy of the wave.

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as from peak to peak or trough to trough.

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch sound.

What is the relationship between amplitude and sound loudness?

Back

The greater the amplitude of a sound wave, the louder the sound is perceived to be.

What is the effect of frequency on pitch?

Back

Higher frequency sound waves produce higher pitch sounds, while lower frequency waves produce lower pitch sounds.

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (solid, liquid, or gas) due to the vibration of particles.
